For the period 03Z August 21 to 16Z August 22, the IMERG real time system experienced an outage of CPC 4-km IR data. Despite the outage, IMERG EARLY and LATE products continued to be produced but users should be aware that the quality of these products during this period may be suspect and should be used judiciously. Furthermore, the products for the first few hours after the outage are less than optimal due to IMERG restart but should be acceptable for most users. Detailed Impacts: (1) The precipitation propagation vectors for the period slowly degraded after 03Z August 21 due to the missing...

L1C NPP ATMS intercalibration table has been updated to account for the NPP ATMS SDR calibration update occurred on March 8, 2017. As a result, PPS will change the L1C NPP ATMS product version to V05B. The downstream L2 - L3 product versions will also be advanced one letter from V05C to V05D.

The TRMM Version 7 Precipitation Radar (PR) products will be superseded by new GPM era products with a reprocessing that will generate TRMM retrievals from the beginning of the TRMM mission to the end of data collection using a single frequency retrieval algorithm similar to that used for GPM Ku. This reprocessing will begin in early July, 2018. Retrievals previously available in the TRMM Version 7 products 2A21, 2A23, 2A25, and 3A25 will be available in the new 2APR and 3PR products. Note that these new GPM era products are in HDF5 format and similar in structure to those used for GPM DPR...
